Yes, I received it in and have carefully gone through it. It is a knockoff but it is very good knockoff. I went through it carefully and noted the items that were not quite right. For starters, the plastic case that it came in is marked Sotac, not Trijicon and there is no paperwork included in the case. As for the sight itself, the Trijicon should turn on when you press on the buttons on either side and it comes on in automatic mode. The clone will only come on when the (+) button is pushed, then gets brighter with each push. The Trijicon has 8 brightness levels and the clone only has five. With the Trijicon, if you press both buttons for 3 seconds, it will shut it down. The clone will only shut down with the (-), taking it down through each step. As pointed out in the video, the battery department is simpler and the adjustment screws are not perfectly centered. But it does have the Trijicon name on it along with the "Made in USA" and "Patent Pending". How the life would be of the light or the battery, I have no idea. I sent a note to the seller, explained what i saw and he quickly sent me a postage paid return label. It is a well made knockoff and after mounting it on a air pistol and trying it out in the basement, I am trying to decide if for the $80, I should keep it on the air pistol or return it. I have to admit that if I was purchasing a used pistol and this sight was mounted on it, I would believe that it was a real one if I had not gone through this.
